Many Honeywell/Ademco Lynx alarm panels (self contained) can be disabled simply by popping off the front from the wall mounted back. The early versions are incredibly simple and fast, later ones are a bit more difficult, but with some brute strength, still too easy.

Hershey Chocolate has changed their formula-use more air in their product-softer, less chocolate consistency. Used to be more solid and price points have remained the same but the size is less than 50% original sizes - why you need to buy more Reeses peanut butter cups for Halloween snack size. at same price.

I currently work in the community sector, we recycle used good and materials, sadly and through noones fault, 85% still ends up in landfill.
I am a wildlife carer, far more animals are euthanised than saved, sad and distressing.

The big one, I worked in international banking and finance for many years, people always base the value of things in currency, bad move, it is not at all real. What happens when currencies go up and down? When shares collapse? Who loses? Who buys both currencies and stock when they are their lowest.
Put it another way, imagine you could manipulate these markets, if you bought low and rising stock, sell them before the peak, then buy them again after. Would you? Think about all the people who have been charged with insider trading. They were just plebs who got to know about things and tried to get iin on the action, they were not the ones behind them who make the decisions.
Our society is like an ant colony, all the worker ans go out and produce, collect and store but hey don't get to keep it. In our case, taxes, changes in government policy, currency and stock fluctuations all funnel the resources up the line, hence the mega rich get richer.
I stopped playing the game when I realised I was just a pawn. I invented my own game with my rules.

I used to rear or help rear broiler chickens for the table. they take approx 7 weeks from day old to be big enough to eat. there are 30,000 to a shed and there supposed to be drug-free for ten days before slaughter. the thing is there at there most crowded and vulnerable in the last 10 days and its the worst time economically to have them die. they always got me to put antibiotics in their water mainly in the last week or so. one other thing even there feathers are fed back to them in powdered form in there food.

In big box retail, rewarding good employees with consistent scheduling is discouraged. In one training class, we were even told to never worry about the "actively engaged" employees, because they would do good work no matter what. I strongly disagree with that sentiment and the practice of inconsistent scheduling about 2 weeks in advance (that could change at the last minute, anyway).
I don't plan on being back in that industry ever again.

Well.. I used to down stack pallets of groceries to bring to the stockpersons. I would sample the products.

I could tell ya, but then I'd have ta kill ya! Nah, I got nuthin. Never worked in food service (where I'm sure there are a million issues) or health care, or the IRS.

In a bacon factory it is common practic to walk over the bacon slabs in your work boots. Discovering that put me off eating bacon. For about a week. Hummm....bacon

That in restaurants, nobody uses tongs to get lemon wedges for drinks.

Archaeologists, believe it or not, do not (usually) have bullwhips nor run around fighting Nazis, not discover vast hordes of gold.

The Catholic clergy have a thing for little boys!

Oh wait...
